SPECIFICATION forming part of Letters Patent No. 731,004, dated June 16, 1903. Application filed February 2l, 1903. Serial No. 144,489. (No model.)

T0 a/ZZ whom it may concern:

Be it known that I, LOUIS WIRscHING, a citizen of the United States, and a resident of New York, in the county ofv New York and; State of New York,have invented certain new and useful Improvements in Thermocauters, of which the following is a specification.

This invention has for its object to provide an im proved thermocauter which is simple in construction and operation and which will,

not be liable to get out of order, the invention consisting of improvements upon the thermocauter forming the subject-matter of Letters'r Patent No. 706,482, granted to me August 5, p 1902. In the thermocauter disclosed in said patent a series of tubes and sets of ports or t openings are provided, through which the gas used in heating the device isadapted to be, passed, the passage of the gas through such tubes and ports being controlled by a valve, l, which in the usual operation of the device is p first positioned so as to cause the gas to pass through one tube and a connecting-port to a l point where it maybe ignited for the pur, pose of initially heating the cauter proper at the exterior side thereof and then positioned I to cut oi the passage of the gas through such p tube and connecting-port and cause it to pass through another or so-called burner-tube"7 i to point within the cauter proper where it; will be caused to ignite from the heat of the cauter as produced by the initial exterior heating thereof, the combustion of the gas continuing at this point and maintaining the cauter at a high degree of heat as long as it is desired to keep the device in operation and the gases and other products resulting from such 4combustion finding escape from the chamber within which combustion takes place through certain exit ports or openings communicating therewith. A thermocauter constructed as thus described and as more fully disclosed in my said prior patent while efficient for the purposes intended is unnecessarily complicated for producing the functions required, and I have found that the same results can be obtained-by the employment of fewer and more simple parts when constructed and combined in accordance with my present invention, as will hereinafter be described in detail in connection with the accompanying drawings, forming a part of this specification, in which- Figure l is a plan view of a thermocauter embodying my invention with an air-forcing apparatus connected therewith. Fig. 2 is a similar View with the thermocauter in central longitudinal section, and Fig. 3 is au enlarged sectional detail of the outer end of the thermocauter.

tube 3, termed the cauter-tube, the opposite or outer end of vwhich is closed, as at 4,

and forms the cauter proper, this outer end or cauter proper in the present case being in the form of a detachable cap, so as to permit ready access being had into the tube, although such cap might, in so far as my present invention is concerned, be formed as an integral part of the said tube. The supporting-shank 2, which is adapted to have connection with some suitable source of gas-supply, is provided with a central bore or passage 5, into which the gas is adapted to be received, and connected with the'shank at the inner end of this bore or passage is a small tube 6 which extends through the outer or cauter tube 3 to a point adjacent to the upper closed end thereof, so as to conduct the gas to such point, which is the point of combustion in the normal operation of the device, as will hereinafter be described. v

In operation the gas received into the bore or passage 5 of the shank 2 passes through the tube 6,'which I term the burner-tube,

and discharges at the upper end thereof into Y the upper closed end of the cauter tube. This end of the cauter-tube not being heated, the gas received thereinto passes downward through the same until it'reaches a circuit of ports or openings 7, formed in the side wall thereof, through which it escapes. This escaping gas in accordance with my presentinvention is utilized for the purpose of initially heating the cauter at the proper point, whereby its heat willignite the gas at-the point of discharge from the end of the burner-tube in a manner as follows: A suitable controller is provided for receiving the gas that escapes through the openings 7 and directing or focusing the flame caused by the combustion IOO of the same upon the cauter, adjacent to the end thereof, as illustrated in Fig. 3, this controller in the present case being in the form of a tube or tubularsleeve 8, slidably mounted upon the cauter-tube 3 and being movable to and from a position over or opposite the said openings 7 therein, the inner diameter of this tubular sleeve being greater than the outer diameter of the cauter-tube, so as to provide a space between such parts for the passage of the gas, the said tubular sleeve being open only at its upper end, through which end the flame is directed, as shown. After the flame thus produced and directed upon the cauter has been continued until the latter has become highly heated, preferably to a red heat, the gas issuing from the end of the burner-tube Within the cauter-tube will become ignited from the heat of the latter, whereupon the controller will be withdrawn from its position opposite the openings 7, so as to expose the same, as shown in Figs. 1 and 2, and permit them to serve as exit-ports for the discharge from the cauter-tube of the gases and other products resulting from the continued combustion at the end of the burner-tube.

Thecontroller 8 may be retained in a desired stationary adjusted position on the canter-tube relatively to the openings 7 by any suitable means, the means as ,herein shown comprising longitudinallyarranged springarms 9, integral with the controller-tube and engaging the cautertube with a yieldingr pressure, so as to frictionally hold said controller-tube in any desired adjusted position thereon. Any suitable means may also be provided for conducting gas to the thermocauter as described, a simple and desirable means being that illustrated in my said prior patent, No. 706,482, and consisting of an aircarbureter l0, to one end of which the thermocauter is connected and to the other end of which a suitable air-forcing device 11 12 is connected, these parts being adapted to operate in the manner as fully set forth in my said prior patent.

YVhat I claim isl. A thermocauter, comprising a cautertube having a port or opening in one side thereof through which the gas conducted into the tube initially escapes, a burner-tube extending into saidcautentube and through which gas is adapted to be conducted, and a vcontroller movable relatively to said opening in the cauter-'tube and coperative therewith to direct the flame produced by the combustion of the escaping gas upon the cauter proper, for the purpose set forth. e

2. A thermocauter, comprising a cautertube having a port or opening in one side thereof through which the gas conducted into the tube initially escapes, a burner extending into said cauter-tube and through which gas is adapted to be conducted, a controller cooperative with said opening in the cautertube to direct the flame produced by the combustion of the escaping gas upon the cauter proper, and means for retaining the controller in a stationary adjusted position relative to the cauter-tube, for the purpose set forth.

3. A thermocauter, comprising a cautertube having a port or opening in one side thereof through which the gas cond ucted into the tube initially escapes, a burner-tube eze tending into said cauter-tube and through which gas is adapted to'be conducted, and a controller cooperative with said opening in the cauter-tube to direct the iiame produced by the combustion f the escaping gas upon the cauter proper, the said controller being in the form of a tube slidably mounted upon the cauter-tube and provided with a springarm or part engaging with the cauter-tube for frictionally holding the controller in adj usted position relatively thereto.

4. A thermocauter, comprising a cautertube having a port or opening in one side thereof through which the gas conducted into the tube initially escapes, a burner-tube extending into said cauter-tube and through which gas is adapted to be conducted, and a controller cooperative with said opening in the cauter-tube to direct the flame produced by the combustion of the escaping gasupon the cauter proper, the said controller being in the form of a tube slidably mounted upon the cauter-tube and being of greater diameter than the outer diameter ofthe cauter-tube so as to provide a space therebetween, one end of said controller-tube being open and the other closed, for the purpose set forth.

Signed at New York, in the county ot' New York and State ot` New York, this 19th day of February, A. D. 1903.
